Currency Values


As for the exchange rate, e.g /CAD, if appreciates in value 10% compared to last year, Is it true that CAD depreciates exactly 10% compared to last year?


yes. mathematically these are just ratios so a movement in one is exactly offset by the other.

No they are not the same. Mathematically they are different.

For example , $2 per 1 EUR now then a year later $4 per 1 EUR. so EUR appreciate 100% ( 4-2)/2.

while USD depreciate (1/4-1/2)/(1/2) = -50% , So not exactly the same. Please add comments to confirm.


you got it, methematically they are not the same.

ahh yes. your correct. sorry

Yep, they are different
